Hi,

I just wonder how to measure the liquid crystal cell gap(Cell gap is thick.)?

I just think that I just measure the empty cell using THz-TDS, and after calculate that using time delay. ( Since the cell gap is empty and filled the air, there will be more time delay. but, I think worried FP effect....)

But, maybe It was wrong.

So, please help me...
